Mandevilla plant named ‘Sunparayokore’

ABSTRACT

A new and distinct cultivar of  Mandevilla  plant named ‘Sunparayokore’, characterized by its compact and vining plant habit; vigorous growth habit; freely branching habit, dense and bushy plant form; dark green-colored leaves; freely flowering habit; long flowering period; and medium-sized dark red-colored flowers.

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘SUNPARAYOKORE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘Sunparayokore’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new compact, freely-branching and vining Mandevilla plants with numerous medium-sized attractive flowers.

The new Mandevilla plant originated from an open-pollination in Higashiomi, Shiga, Japan in April, 2006 of a proprietary selection of Mandevilla hybrida identified as code number M37-mt1, not patented, as the female, or seed parent with an unknown proprietary selection of Mandevilla hybrida, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in October, 2007.

Asexual reproduction of the new Mandevilla plant by cuttings in Higashiomi, Shiga, Japan since October, 2007 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunparayokore’. These characteristics in combination distinguish ‘Sunparayokore’ as a new and distinct Mandevilla plant:

-   -   1. Compact and vining plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit, dense and bushy plant form.     -   4. Dark green-colored leaves.     -   5. Freely flowering habit.     -   6. Long flowering period.     -   7. Medium-sized dark red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the female parent selection. Plants of the new Mandevilla differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla are more vining than plants of         the female parent selection.     -   2. Plants of the new Mandevilla have ovate-shaped flower petals         whereas plants of the female parent selection have         spatulate-shaped flower petals.     -   3. Plants of the new Mandevilla and the female parent selection         differ in flower color as plants of the female parent selection         have light red purple-colored flowers.

Plants of the new Mandevilla can be compared to plants of the Mandevilla ‘Sunparacore’, disclosed in U.S. Plant patent application Ser. No. 13/374,302. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Mandevilla differed from plants of ‘Sunparacore’ in the following characteristics:

-   -   1. Plants of the new Mandevilla had longer and thicker lateral         branches with longer internodes than plants of ‘Sunparacore’.     -   2. Plants of the new Mandevilla had elliptic-shaped leaves         whereas plants of ‘Sunparacore’ had obovate-shaped leaves.     -   3. Plants of the new Mandevilla flowered later than plants of         ‘Sunparacore’.     -   4. Plants of the new Mandevilla had smaller flowers than plants         of ‘Sunparacore’.     -   5. Plants of the new Mandevilla had longer peduncles than plants         of ‘Sunparacore’.
